Due to the statistical distribution of the measured values for pulse
oximetry sensors, on average two thirds of all measurements are
within the ±arm value of CO oximeters as a reference method (see
table). To determine bpm accuracy, comparative measurements
were performed with an original sensor and original monitor.
